SS 4.7 and SlingPlayer

I had my slingplayer running just fine with SS 4.6. I upgraded to 4.7 and liked a lot of it. I tried to run slingplayer and it starts, starts to open the first screen, and exits. I've uninstalled/reinstalled, deleted data, re-downloaded and re-installed SS 4.7 and it is always the same. I restore my SS 4.6 and all is good, install SS 4.7 and slingplayer won't work. Does anybody have any suggestions as to why?
